I changed my review after i wrote it two days after receiving it!!! Now after having this for over a month now there is a significant dent in it from my sleeping position that wont bounce back as it isn't memory foam. which is annoying that a mattress like this would even be made. I have already had to buy a mattress topper that isn't that effective as the dent is now so significant. I wouldn't recommend this mattress. It is a very firm mattress, if that's what you want then this is for you. Keep in mind it isn't memory foam but is a foam mattress, so it wont bounce back.
